(Reuters) - U.S. President Donald Trump is readying an announcement on auto levies as soon as Wednesday, Bloomberg News reported, citing people familiar with the matter.

The report, pegged to unnamed sources, follows Trump's comments to reporters on Monday that the long-promised tariffs on imported cars could come this week, even before a swath of reciprocal tariffs aimed at the countries responsible for the bulk of the U.S. trade deficit on April 2.

The White House has given no specific timetable for the announcement or details on the extent of the expected tariffs. "I'd take him at his word," one administration official told Reuters when pressed for when Trump might announce auto tariffs.

Bloomberg reported that one person familiar with the matter said Trump's plans could shift.

Trump in February floated the idea of a 25% tariff on imported vehicles but has offered no other details.
